Recurrent seizures in tramadol intoxication: implications for therapy based on 100 patients.
Tramadol is an atypical opioid analgesic used in the treatment of mild to moderate pain. Despite being a GABA(A) agonist, seizures are a prominent complication with its therapeutic use, abuse or overdose. For patients who have had a tramadol-induced seizure, the likelihood of recurrent seizures and the need for emergent anticonvulsant prophylaxis is unknown. ⋯ By our standard clinical protocol, none were treated with seizure prophylaxis after their first seizure. Only 7% had recurrent seizures and all patients recovered without sequelae. Because of the low risk of multiple seizures in tramadol poisoning and the lack of morbidity in patients who do seize, it appears to be unnecessary to administer prophylactic anticonvulsant therapy in patients with tramadol poisoning, even if they have an initial seizure.
